Decomposition means a reactant is broken down. Therefore, the Li2CO3 equation is the correct one.
Answer: [tex]Li_2CO_3\rightarrow Li_2O+CO_2[/tex]
Explanation:
Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.
[tex]A\rightarrow B+C[/tex]
1. [tex]Li_2CO_3\rightarrow Li_2O+CO_2[/tex] is an example of decomposition.
2. [tex]Zn+HCl\rightarrow ZnCl_2+H_2[/tex] is an example of single replacement reaction in which more reactive element displaces the less reactive element from its salt solution.
3. [tex]Na_2O+CO_2\rightarrow Na_2CO_3[/tex] is an example of synthesis reaction in which two reactants are combining to form one product.
4. [tex]C_6H_{12}O_6+O_2 \rightarrow CO_2+H_2O[/tex] is an example of combustion in which fuel is reacted with oxygen to form carbon dioxide and water.
